On the 2007-2011 Chevrolet Silverado AFM V8 (RPO L94, LZ1, LC9, LH6, L76, L92, LFA, LMG or LY5), gM bulletin 10-06-01-008H applies to certain 2007-2011 Chevrolet Silverado 1500 trucks with listed Active Fuel Management V8 engines and specific build-date breakpoints. GM describes oil pulled through the PCV system or oil spray from the AFM pressure-relief valve forming deposits in the piston-ring grooves. Customers may report excessive consumption, rough running, a service-engine-soon light, or cracked or fouled spark plugs, commonly after about 30,000-40,000 miles. The bulletin defines excessive consumption for this procedure as more than one quart in 2,000-3,000 miles; it does not establish that every listed truck is affected.
Common Symptoms
Oil consumption greater than one quart in roughly 2,000-3,000 miles
Oil puddling in the intake manifold from PCV pull-over
Rough running or service-engine-soon light
Cracked or carbon-fouled number 1 or number 7 spark plug
How to Fix
Have a qualified technician verify the VIN, engine RPO, build date, PCV operation, intake-manifold oil and actual consumption against bulletin 10-06-01-008H. Depending on the documented condition and build breakpoint, GM directs technicians to install the correct updated left valve cover, clean the pistons, install the AFM oil deflector where specified and re-evaluate consumption. If consumption remains greater than one quart per 2,000 miles after the bulletin procedure, GM states that piston-and-ring replacement may be required. Do not buy a generic AFM delete kit from this card.
